Following your study of this unit, you should be able to
1. state the law of
conservation of mass, law of constant composition, and law of multiple
proportions, and use experimental data to verify
the laws.
2. tell the number of atoms of each element in a formula unit for a compound,
given the
chemical formula. Write chemical formulas, given the number of atoms of each
constituent element in
the formula unit of the compound.
3. describe significant experiments that led to
the current model of the atom and explain
how each contributed to the current understanding of atomic structure.
4. describe mass differences and charge differences among electrons, protons and
neutrons.
5. describe the arrangement of electrons, protons and neutrons in atoms.
6. define isotope, atomic number and mass number in terms of the number of electrons,
protons and neutrons.
7. calculate numbers of electrons, protons, and neutrons
in an atom, given the atomic
number and the mass number.
8. calculate the
average atomic mass given the isotopic abundance.
9. define the terms radioactivity
and radioisotope
10. distinguish between alpha, beta, and gamma radiation
11. write symbols for alpha particle, beta particle (electron), proton, neutron, and
positron.
12. write and balance nuclear equations representing alpha and beta decay
13. distinguish between nuclear fission and nuclear fusion.
14.
identify those elements that form stable diatomic molecules.
15. distinguish between
the meaning of the terms atom, molecule and ion.
16. locate groups of atoms in the
periodic table using two different organizing schemes:
a--metals, nonmetals and metalloids
b--these named chemical families: alkali metals, alkaline earth metals,
halogens, noble gases
17. identify the 'normal' ionic charge for the alkali metals,
alkaline earth metals, and
halogens.
18. write the formula for an ionic compound given the name and charge
of both cation and anion.
19. predict whether any given pair of elements will form
an ionic or a covalent
compound.
20. name simple ionic and covalent compounds,
given the formula.
21. write the formula for simple ionic and molecular compounds
given the IUPAC name.
